/*
 * ARM timer implementation, found in Integrator, Versatile and Realview
 * platforms.  Not all platforms support all registers and bits in these
 * registers, so we mark them with A for Integrator AP, C for Integrator
 * CP, V for Versatile and R for Realview.
 *
 * Integrator AP has 16-bit timers, Integrator CP, Versatile and Realview
 * can have 16-bit or 32-bit selectable via a bit in the control register.
